Xa kuziwa kwii-sealants kunye ne-adhesives, amagama amabini aqhelekileyo ahlala edideka - i-RTV kunye ne-silicone. Ngaba ziyafana okanye kukho iiyantlukwano eziphawulekayo? Ukuze wenze isigqibo esinolwazi malunga nokukhetha imveliso efanelekileyo kwiimfuno zakho ezithile, makhe sinciphise ihlabathi elingaqondakaliyo le-RTV kunye ne-silicone.
Iinkcazelo zeRTV kunye neSilicone:
RTV, okanye i-vulcanization yobushushu begumbi, ibhekisela kwi-sealant okanye i-adhesive ephilisa kwiqondo lokushisa ngaphandle kwesidingo sokufudumala.Iisilicones, kwelinye icala, ziipolima zokwenziwa ezenziwe ngesilicon, ioksijini, ihydrogen, neeathom zecarbon. Ngenxa yeempawu zayo ezininzi, isetyenziswa ngokubanzi njenge-sealant okanye i-adhesive.
Ukuqulunqwa kwemichiza:
Ngelixa zombini i-RTV kunye ne-silicone ziyi-sealants, zineendlela ezahlukeneyo zeekhemikhali. Ii-RTVs ngokuqhelekileyo ziquka i-polymer esisiseko edityaniswe nezihluzi, iiarhente zokunyanga kunye nezinye izongezo. Iipolymers ezisisiseko zinokwahluka kwaye ziquka izinto ezifana ne-polyurethane, i-polysulfide okanye i-acrylic.
I-silicone, kwelinye icala, yinto ephuma kwi-silicon. Ihlala ixutywa kunye nezinye iikhompawundi ezifana ne-oksijini, i-carbon kunye ne-hydrogen, okubangelwa imveliso eguquguqukayo kunye neyokugqibela. Inhlanganisela ekhethekileyo yezi zinto ivumela i-silicones ukuba igcine iipropati zabo phantsi koluhlu olubanzi lweemeko zokusingqongileyo.
Iimpawu kunye nezicelo:
Enye yeeyantlukwano eziphambili phakathi kwe-RTVs kunye ne-silicones ziipropati zabo kunye nokusetyenziswa.
1. RTV:
- Ukwazi ukumelana neekhemikhali, i-oyile kunye namafutha.
-Inika amandla aphezulu kunye nokuguquguquka.
- Ngokuqhelekileyo isetyenziswa kumashishini afana neemoto, ukwakhiwa kunye nokuvelisa.
-Igqwesileyo yokutywina i-seams, izithuba zokuzalisa kunye ne-bonding substrates.
2. Ijeli yesilika:
-Ukumelana kakhulu nobushushu obugqithisileyo, imitha ye-UV, ukufuma kunye nemozulu.
- Iimpawu ezigqwesileyo zokufakelwa kombane.
- Fumana izicelo kwiinkalo ezifana ne-electronics, amashishini ezonyango kunye ne-aerospace.
- Ukutywinwa, ukutyumba, ukukhupha i-gasket kunye ne-bonding apho ukuchasana neemeko ezinzima kufuneka.
Inkqubo yokunyanga:
Omnye umahluko obalulekileyo phakathi kwe-RTV kunye ne-silicone yinkqubo yabo yokunyanga.
1. RTV:
- Ukufuma kwe-atmospheric okanye ukudibana komphezulu kuyafuneka ukuqalisa inkqubo yokunyanga.
- Ixesha lokunyanga ngokukhawuleza, ngokwesiqhelo kwiiyure ezingama-24.
- Inokufuna iprimer ukubambelela kwezinye izinto.
2. Ijeli yesilika:
- Ukunyanga ngokufuma emoyeni okanye ngokusebenzisa i-catalyst.
- Ixesha lokunyanga lide, ukusuka kwiiyure ezimbalwa ukuya kwiintsuku ezininzi, ngokuxhomekeke kwizinto ezifana nobushushu kunye nokufuma.
- Ibambelela kwiindawo ezininzi ngokubanzi ngaphandle kwesidingo se-primer.
Ukuqwalaselwa kweendleko:
Xa ukhetha phakathi kwe-RTV kunye ne-silicone, ixabiso lidla ngokuba yinto ephambili.
1. RTV:
- Ihlala ineendleko ezisebenzayo kune-silicone.
- Inikeza ukusebenza kakuhle kuluhlu lwamaxabiso.
2. Ijeli yesilika:
- Ngenxa yeempawu zayo eziphezulu kunye nokusebenza, ixabiso liphezulu kancinci.
-Evunyiweyo kwizicelo ezifuna ukuxhathisa kwiimeko ezinzima.
Ukushwankathela, nangona i-RTV kunye ne-silicone zinento efana nayo njengama-sealants, ukungafani kwazo kukwi-chemical composition, ukusebenza, ukusetyenziswa, inkqubo yokunyanga kunye neendleko. Ukuqonda ezi nuances kubalulekile ekukhetheni imveliso eyiyo kwiimfuno zeprojekthi yakho. Nokuba ukhetha i-RTV ukuqina kwayo okanye i-silicone ukuqina kwayo, ukwenza isigqibo esinolwazi kuya kukunceda ufezekise ngempumelelo iziphumo ozifunayo.
